Don't use MTN, just don't.

<p>So I have collection companies harrasing me for a supposed outstanding balance yet I cancelled my contract a year ago and have the email confirmation from MTN when I did so.</p> <p> </p> <p>I've emailed MTN customer care numerous times concerning this, with the proof of cancellation, but get ignored. Phoning MTN is futile as after I enter the cell phone number in question the automated phone system says thank you good bye.</p> <p> </p> <p>Please assist.</p>
